You can either unpack the target at generation time (recommended).
Or you could create an INTERFACE target instead.
The first solution is recommended as I believe it's important to have
access to all the sources (for IDEs for example) before actually
starting the build process.

Hi @all,
I’ve tried importing an external library like that:
stackoverflow.com/questions/31274577
I have the same use case, except that my custom target does not call
make but does unpack a tar archive containing headers and .a.
My problem is that the step
“
# specify where the library is and where to find the headers
set_target_properties(lib2
PROPERTIES
IMPORTED_LOCATION ${LIB_FILE}
INTERFACE_INCLUDE_DIRECTORIES ${LIB_HEADER_FOLDER})
“
fails. When running cmake, I get an error that the header dir
specified with “INTERFACE_INCLUDE_DIRECTORIES” does not exist.
“
CMake Error in src/CMakeLists.txt:
Imported target "whatever" includes non-existent path
"/path/to/include"
in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:
* The path was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and references files it does not
provide.
“
This is true, as the header path is only generated when running the
unpack target. Is there a way to tell cmake to skip this check?
Thanks!
Regards,
Martin
