[CMake] integrating cmake configured library with other GNU based build system?

[Burlen Loring]

Hi All,

Can cmake generate .pc files? Can cmake generate .la files (gnu 
convenience libraries)? Cmake internally generates all the requisite 
info, how can it be accessed?

I have to integrate a cmake based library into a GNUMake build. The 
project has a cmake config file 
<https://gitlab.kitware.com/sensei/sensei/blob/master/CMake/SENSEIConfig.cmake.in> 
which works great with cmake's find_package command when integrating 
with another project using cmake. What do we do when a GNUMake based 
project wants to import our library?

I hacked a cmake script 
<https://gitlab.kitware.com/sensei/sensei/blob/master/tools/sensei_config/CMakeLists.txt> 
to recursively walk our libraries dependencies and inspect 
INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_LINK_LIBRARIES to put 
together a unique list of libraries and include dirs, which can be used 
to generate the necessary info. Unfortunately so far I can only make it 
work as an external cmake project which is configured after we install 
our library.

I would like to have a solution that generates the GNU compatible 
configuration file (.pc,.la, etc)  integrated into our build rather than 
as an additional separate post install step. How have others solved this 
issue?

Thanks
Burlen
