CMake Error at CMakeLists.txt:101 (MESSAGE):

-- Configuring incomplete, errors occurred!

I have also tried running cmake .. -DBOOST_INCLUDEDIR=/usr/include/boost/ -DBOOST_LIBRARYDIR=/usr/lib -DPYTHON_LIBRARIES=/usr/lib/python2.7 -DPYTHON_INCLUDE_DIRS=/usr/include/python2.7 -DBOOST_ROOT=/mnt/MEGA/src/boost_1_65_0, with the same result.

https://github.com/LuxCoreRender/LinuxCompile does not work either, due to the following issue: LuxCoreRender/LinuxCompile#8

It looks like my re-compilation of boost to use python3_7 through my package manager didn't actually use it, so I will try to do so again with a bit of a change to my USE flags first.

I cannot use precompiled binaries, as I am attempting to modify the source code to use nearest neighbor sampling instead of terrible, horrible bilinear filtering.

Edit: It looks like Boost doesn't support python 3.7?

According to #205, the problem is https://github.com/LuxCoreRender/LuxCore/blob/master/cmake/Dependencies.cmake#L69. Deleting python${PYTHON_V} and numpy${PYTHON_V} does indeed fix it, and I can also replace python${PYTHON_V} with python-3.5 and have it work fine. I do not, however, know how to make it properly depend on numpy yet, though.

@happysmash27 For boost-1.65 you can replace ${PYTHON_V} by -3.{5,6}, depending on which python you are using, for both, the python and the numpy component.
However, boost-1.65 doesn't have python-3.7 support in gentoo, so that's no possible.
You might want to take a look at https://github.com/waebbl/waebbl-gentoo/tree/master/media-gfx/luxcorerender for an ebuild which used to work with boost-1.65 (and still should). Note however, that it's broken for boost-1.70, if you happen to have boost upgraded already.

I assume we can close this one.

well, something like this hit my machine x86 Slackware too. I also hacked cmake/Dependencies.cmake for removing numpy${PYTHON_V} and replacing python${PYTHON_V} with just python37 . Note I have TWO versions of python installed, 2.7 and 3.7, and boost 1.69 just recompiled with numpy3, installed into python3 via pip3 install numpy .....
