Summary0014793: CMake on Linux can not produce Watcom Wmake files or use Watcom as compiler
DescriptionDear all,

I am playing with trying to build ReactOS using Open Watcom (the v2 fork) and would love to be able to do so natively (from Linux) using Open Watcom as a win32 cross compiler instead of MinGW. My forked sources can be found at [1].

Strangely, configuring with CMake either running under Wine or under Windows allows for selecting Watcom as compiler / make file style, but not when run under Linux. Also if CC and CXX is set to the watcom compilers and CMake is told to make "Unix makefiles", CMake detects them during configuration but the actual build falls back to the default cc (gcc).

1: https://github.com/staalmannen/reactos/tree/reactow [^]
Steps To Reproduce* Install Open Watcom on Linux, try to configure a CMake project to use Watcom as compiler / Make file style.

If example sources is the "ReactOW" above, simply do something like:

WATCOM=/opt/watcom bash ../reactos/configure.sh

cd to host-tools
make
cd to reactos
make

you will see that it falls back to gcc.

from a build directory next to the checked out sources.
