c++ - CMake -- Add all sources in subdirectory to cmake project -


Complying with this question:

What is the best approach (perhaps using the FILE command ?) To select all .cpp and .h files in the subdirectory and add them to the defined SOURCE variable in the root directory?

For example, above the answer to the question: 

  set (source $ {source} $ {CMAKE_CURRENT_SOURCE_DIR} /file1.cpp $ {CMAKE_CURRENT_SOURCE_DIR } /file2.cpp PARENT_SCOPE) set (header $ {header} $ {CMAKE_CURRENT_SOURCE_DIR} / file1 .hpp $ {CMAKE_CURRENT_SOURCE_DIR} /file2.hpp PARENT_SCOPE)

to do something like this possible? 

  file (GLOB SUB_SOURCES * CPP) set (source $ {source} $ {CMAKE_CURRENT_SOURCE_DIR} / $ {SUB_SOURCES} PARENT_SCOPE)

What is the best way

I think what you're looking for is the aux_source_directory command.

aux_source_directory Locate all source files in a directory.

aux_source_directory ()

List of all source files included in the specified directory and the list provided in the store. This order is intended to be used by projects that use clear templates instantly . Template Instant Files can be stored in the "Template" subdirectory and this command can be used automatically to avoid listing these commands manually.

This is the list of source files for the library or the executable goal, though it seems to be working, there is no way to create a build system that knows that when a new source file has been added. Usually the Generated Building System knows that when it needs to run Simmer again because the CMakeLists.txt file has been modified to add a new source. When the source is added to the directory without modifying this file, then one has to do it again to manually create the build system that includes the new file manually.

Your CMakeLists.txt will look like this in the subdirectory: 

  set aux_source_directory ($ {CMAKE_CURRENT_SOURCE_DIR} SUB_SOURCES) (source $ {source} $ { SUB_SOURCES} PARENT_SCOPE)

The recommended method is however, as you see from documentation, change the CMakeLists.txt file to list files individually within CMakeLists.txt The cmake turns on.

I hope it was helpful and at the point.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title ').
