KMyMoney build problem

[aga]

I've not built KMM for some while and am now having a problem.

CMake Error at CMakeLists.txt:72 (find_package):
   By not providing "FindQGpgme.cmake" in CMAKE_MODULE_PATH this project has
   asked CMake to find a package configuration file provided by 
"QGpgme", but
   CMake did not find one.

I'm using Linux Mint 17.3 and can't find a dev package.

Thanks

Allan
