I've picked this up again with OpenBSD 6.6 amd64, and after installing Gnu
CC 8.3.0 et al:
openbsd66$ egcc -v
Using built-in specs.
COLLECT_GCC=egcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-openbsd6.6/8.3.0/lto-wrapper
Target: x86_64-unknown-openbsd6.6
Configured with: /usr/obj/ports/gcc-8.3.0/gcc-8.3.0/configure
--with-stage1-ldflags=-L/usr/obj/ports/gcc-8.3.0/bootstrap/lib --verbose
--program-transform-name='s,^,e,' --disable-nls --with-system-zlib
--disable-libmudflap --disable-libgomp --disable-libssp --disable-tls
--with-gnu-ld --with-gnu-as --enable-threads=posix --enable-wchar_t
--with-gmp=/usr/local --enable-languages=c,c++,fortran,objc,ada
--disable-libstdcxx-pch --enable-default-ssp --enable-default-pie
--without-isl --enable-cpp --prefix=/usr/local --sysconfdir=/etc
--mandir=/usr/local/man --infodir=/usr/local/info --localstatedir=/var
--disable-silent-rules --disable-gtk-doc
Thread model: posix
gcc version 8.3.0 (GCC)
Modifying CMakeCache.txt to point at gcc 8.3.0 and egfortan over in
/usr/local/bin, and adding the global option -fopenmp to the compilers, we
get this result:
openbsd66$ cmake ../src
-- The C compiler identification is GNU 8.3.0

-- The Fortran compiler identification is GNU 8.3.0

The C compiler

It fails with the following output:

I grepped about for a bit for information about where the missing
libgomp.spec file should live, and I couldn't find anything. Searching the
system for .spec files yields the following:
openbsd66# find / -depth -name "*.spec"
/home/larry/projects/wsjt-wsjtx/src/boost/tools/build/src/engine/boost-jam.spec
/usr/local/lib/libitm.spec
/usr/local/lib/libgfortran.spec
/usr/local/share/libxml2/docbook.spec
/usr/local/share/libxml2/docbook-xsl.spec
Makes it look like maybe OpenMP support is only partially present?
