CMake将文件复制到当前工作目录Linux

Question

I want to copy a shared library that is in my source directory to the program's running directory.

In linux we get there using /proc/self/cwd/

And I am looking in: /proc/self/cwd/CMakeFiles

Compiled source files are located here, but I do not see my library.

What is the CMake command to do this?

I already tried: set(CMAKE_LIBRARY_PATH ./)

You should look at the manual section Variables that Provide Information . In particular, the variables CMAKE_BINARY_DIR and CMAKE_RUNTIME_OUTPUT_DIRECTORY are useful as destination locations to your build tree. The variables CMAKE_SOURCE_DIR and CMAKE_CURRENT_SOURCE_DIR are useful for source locations.

Typically, when I am in my top-level project source directory, myproject containg the top-level CMakeLists.txt file, I use a sibling folder myproject-build . For example

cd $HOME/myproject
mkdir ../myproject-build
cd ../myproject-build
cmake ../myproject

then

• CMAKE_SOURCE_DIR=$HOME/myproject
• CMAKE_BINARY_DIR=$HOME/myproject-build

Does this help?
