cmake error in 3.0.12 when building without C++

[eschnett]

I am building Notcurses 3.0.12 with the options

FLAGS=(-DCMAKE_TOOLCHAIN_FILE=${CMAKE_TARGET_TOOLCHAIN}
       -DCMAKE_INSTALL_PREFIX=${prefix}
       -DCMAKE_BUILD_TYPE=Release
       -DBUILD_EXECUTABLES=ON
       -DBUILD_SHARED_LIBS=ON
       -DUSE_CXX=OFF
       -DUSE_DOCTEST=OFF
       -DUSE_MULTIMEDIA=${multimedia}
       -DUSE_PANDOC=OFF
       -DUSE_POC=OFF
       -DUSE_QRCODEGEN=OFF
       -DUSE_STATIC=OFF
       )

which specifies both -DUSE_CXX=OFF and -DUSE_STATIC=OFF.

This fails with the error:

[19:30:14] CMake Error at CMakeLists.txt:602 (target_compile_options):
[19:30:14]   Cannot specify compile options for target "notcurses++-static" which is not

sacre bleu!

do you happen to know whether this is a regression in 3.0.12? if not, no problem.

[dankamongmen]

verified in 3.0.12

[dankamongmen]

i think i've got a fix

[eschnett]

Yes, this is a regression. It's not important at the moment – we have a patch and are using 3.0.12 just fine. I opened this issue mostly for future releases.

[dankamongmen]

no thank you very much for opening it! just if it's a regression (as indeed it is) i think that justifies a quick release to get the fix out.

[dankamongmen]

yeah i'm gonna put out 3.0.13 for this.
