I fixed a similar error on MSVC once. MSVC encodes the return type in the mangled symbol, while gcc does not, and the build fell over on MSVC because we had two different declarations for Pgm(), one returning a reference to PGM_BASE, the other returning a reference to a compatible type (so this wasn't a runtime problem). My suspicion is that something similar is going on here. This could be something stupid even like a mismatch in compiler flags (which are a mix of CMAKE_CXX_FLAGS, CMAKE_SHARED_LINKER_FLAGS, CMAKE_MODULE_LINKER_FLAGS and CMAKE_EXE_LINKER_FLAGS). Compiling with -flto on gcc gives a few warnings[1] about different types being used in the 3D viewer, usually related to GLM vector types (so presumably different translation units use different preprocessor macros when including GLM), but nothing Kiface related (this wouldn't catch any mismatch in modules that are not linked together though).
