How to get the list of files that will be installed when installing a CMake component

Is there any way to know programmatically (in CMake) what files will be installed if a COMPONENT is installed (something like a get_property of component)?

Currently, I am installing a COMPONENT to a temporary location for packaging (not using CPack for packaging) and then packaging using custom commands. I'm invoking the following command during packaging in CMake.

cmake -DCOMPONENT=my_test_component 
-DCMAKE_INSTALL_PREFIX=${TMP_PACKAGING_ROOT}
-P ${CMAKE_BINARY_DIR}/cmake_install.cmake

I wanted to know if it is possible to get the list of files so that I can only include those files explicitly in the package? Or possibly add them as outputs to the custom command?

Solution

  • The only way to know it seems to be by reading the install_manifest_${component}.txt which will have all the list of files that will be installed when we install a CMake component.
