如何使用cmake复制dll？ [英] How to copy the dll's using cmake?

问题描述

在构建解决方案时，我必须将dll复制到文件夹中。 cmake的结构如下：

I have to copy dll's to a folder while building my solution. The structure of cmake as follows:

    D:/src/cmakeLists.txt
    D:/target/runtime/bin
    D:/repos/stable/compiler/xyz.dll

所以我要将xyz.dll复制到 D：/ target / runtime / bin。我在cmake中做了如下操作：

So, i want to copy xyz.dll to "D:/target/runtime/bin" . I did as follows in cmake:

add_custom_command(TARGET performance POST_BUILD        
COMMAND ${CMAKE_COMMAND} -E copy_if_different  
    "${PROJECT_SOURCE_DIR}/libs/xyz.dll"  
    $<TARGET_FILE_DIR:performance>)

但是它没有复制任何dll。所以，建议我如何实现它。我对cmake不太熟悉。因此，请提出建议。

But it did not copied any dll. So, suggest me how do i achieve it. I am not much familiar with cmake .So, please suggest.

推荐答案

我使用 configure_file（）命令。它将在cmake生成步骤中复制文件。

I use the configure_file() command for that purpose. It copies the file during the cmake generate step.

尝试类似

configure_file("${PROJECT_SOURCE_DIR}/libs/xyz.dll" $<TARGET_FILE_DIR:performance> COPYONLY)
