Re: [CMake] find_package and get_target_property

[CHEVRIER, Marc]

Using ‘install(EXPORT …)’ you can generate required files to manage imported 
targets BUT building and exporting targets must be done in a different build 
environment from the one which imports the targets.

Ah I see. In this case, the Libraries I'm depending on are generated, built and 
installed using CMake. I'm hoping that CMake is able to generate the 
Find.cmake for me with the appropriate imported targets, as long as 
INSTALL(export...) was used properly...?

Not necessarily. It depends how the package was created. Using EXPORT is a 
possibility to generate a Config file for the package.
Another possibility is to have a FindLibA.cmake file which creates an imported 
target by using command ‘add_library (LibA SHARED IMPORTED)’.

Thanks Marc. I assume you mean the library does not export its targets 
properly? Something like this:

# https://cmake.org/Wiki/CMake/Tutorials/Exporting_and_Importing_Targets
install(TARGETS generator DESTINATION lib/myproj/generators EXPORT 
myproj-targets)
install(EXPORT myproj-targets DESTINATION lib/myproj)

In this case, you have to rely on variables (like LibA_LIBRARIES and so on…).

Subject: [CMake] find_package and get_target_property

Hi,

I am successfully able to find a package using find_package(LibA) but I cannot 
do a get_target_property on the package as I get the error:

get_target_property() called with non-existent target "LibA"

How do I go about the target properties for a package?
