[PROJ] cmake find_package() fails to find PROJ6 installed with MacPorts

[Tom O'Reilly]

I'm running cmake 3.22.4 on MacOS 11.6. 
I installed proj6 with " sudo port proj6" which looks to be [ https://proj.org/install.html | the proj-recommended way to install with MacPorts ] . I see the proj6 include/ and lib/ subdirectories in /opt/local/lib/proj6, and set PROJ6_ROOT to /opt/local/lib/proj6 accordingly in my applications's CMakeLists.txt. 

But CmakeLists.txt is unable to find proj on the system. Th e [ https://proj.org/development/cmake.html | proj page also says ] : 





The recommended way to use the PROJ library in a CMake project is to link to the imported library target PROJ::proj provide by the CMake configuration which comes with the library. Typical usage is: 




find_package(PROJ CONFIG REQUIRED) 




However find_package() cannot find PROJ or PROJ6 on my system - find_package() exits with this message: 

CMake Error at CMakeLists.txt:95 (find_package): 

Could not find a package configuration file provided by "PROJ6" with any of 

the following names: 



PROJ6Config.cmake 

proj6-config.cmake 




Moreover I do not see any files named "proj*.cmake" in /opt/local - somehow installing proj6 with MacPorts did not include this package information? What am I doing wrong? 

Any help much appreciated! 




Thanks 

Tom
