cmake UnrealEngine seems to take several hours to complete, which is far, far, far beyond anything I’ve ever experienced. Generates a few hundred megs of cmake data. :-S
well, I guess if ultimately we’re running UBT, then I need to dig into UBT and figure out how to swap out what it’s building everything with. Ultimately, I need to build everything with a customer supplied toolchain, not the defaults. It seems that this should work with cmake/make, but it ends up attempting to build with system compiler, instead of toolchain compiler. :-S
i was able to get the process to work outside of the automated build system (bitbake) by doing
mkdir build
cd build
cmake ..
make UE4Editor-Linux-Debug
… or at least, it seemed to. when I attempted the same thing in bitbake, i ended up with it providing all the compiler options as expected, but using the wrong compiler. And I guess I know now, that that would be because UBT is selecting and executing the compiler, and ignoring what is configured via cmake.
