Shared libraries (BUILD_SHARED_LIBS) are only supported on Windows, Linux,

fixed with

	--targetSystem='Linux;UNIX' CMAKE_SYSTEM_NAME=Linux BUILD_SHARED_LIBS=ON   \

Now have some problems with right ldc2.conf:

.PHONY: hello
hello: $(ROOT)/bin/hello
$(ROOT)/bin/hello: hello/hello.d ldc2.conf
	$(XPATH) ldc2 -mtriple $(TARGET) -of=$@ $< && file $@

project-local: ~/player/ldc2.conf

"i686-.+-linux-musl":
{
    switches = [
        "-mcpu=i686",
        "-I%%ldcbinarypath%%/../import",
        "-gcc=i686-linux-musl-gcc"
    ];
    lib-dirs = [
        "/home/ponyatov/player/root/lib"
    ];
}

ldc2 -mtriple i686-linux-musl -of=/home/ponyatov/player/root/bin/hello hello/hello.d && file /home/ponyatov/player/root/bin/hello

/home/ponyatov/player/host/lib/gcc/i686-linux-musl/12.3.0/../../../../i686-linux-musl/bin/ld: cannot find -lunwind: No such file or directory
