Sorry about the late reply, the build is now generator agnostic. However, the flags seem to have to be set manually for some reason, otherwise namcap shows corresponding warnings.

Thank you for providing this package. Unfortunately, the package unconditionally assumes (Unix) Makefiles CMake generator which causes the following error every time I update:

-- Configuring done (2.4s)
-- Generating done (0.0s)
-- Build files have been written to: /home/<user>/Projects/highs/src/HiGHS-1.7.1/build
==> Starting build()...
make: *** No targets specified and no makefile found.  Stop.
==> ERROR: A failure occurred in build().
    Aborting...

because I have CMAKE_GENERATOR=Ninja defined in my ~/.bashrc.

Resolving this issue requires replacing all make calls either by cmake --build or cmake --install to be generator agnostic. I suggest the following changes:

     cd "$srcdir/${_pkgname}-${pkgver}"

I took here the liberty to further simplify the build recipe. Particularly, setting linker flags is unnecessary since CMake pulls these from LDFLAGS anyway.

@ducakar: Sorry for the late reply. To improve build times I suggest you visit the makepkg page in the wiki:

https://wiki.archlinux.org/title/Makepkg

The TLDR is that you should set MAKEFLAGS="-j<N>" in /etc/makepkg.conf to enable parallel compilation system wide for your machine, which should make more sense than fiddling with individual packages (and including ninja as additional dependency).

This builds in only one thread. Could you pass the -j <N> parameter for more parallel jobs or - even better - ninja?

@belgium: I updated to the latest release (1.2.1 currently), which compiles correctly on my machine. Beware that there are always a lot of warnings during the compilation, even if there are no downright errors.

doesn't compile, many errors
