Thank you Konstantin. get_target_properties(...) works very well.

If  find_package(LibA) provides you target "LibA" (i.e., cmake code under "if 
(TARGET LibA)"
condition is being executed), you can query various properties from it and 
expect them to
have sane values. See documentation on cmake properties.

If there is no LibA target, it probably means that find_package(LibA) is 
implemented via
FindLibA.cmake module, and you can only use variables that it sets (usually 
documented in
the beginning of module)

[CMake] Querying CMake variables of external CMake projects

[Saad Khattak]

Hi,

Say I find LibA using find_package(LibA) and I now have access to LibA_DIR,
which is the build folder of LibA. Is there a way I can query additional
variables, such as LibA's source directory, install directory etc. i.e.
variables that are defined by CMake when LibA was being generated/built by
CMake?

Thanks,
Saad
