[Buildroot] [PATCH 0/3] package/pkg-cmake.mk: host: build shared as default

[Michael Nosthoff]

this is a follow-up to this discussion/investigation
 http://lists.busybox.net/pipermail/buildroot/2020-September/291494.html

first for doxygen and clangd/lld -DBUILD_SHARED_LIBS is enforced to =OFF.
finally the default flag -DBUILD_SHARED_LIBS=ON is set.

Michael Nosthoff (3):
  package/doxygen: disable shared libs for host
  package/{clang, lld}: host: disable shared_libs
  package/pkg-cmake.mk: build host with shared libs

[Buildroot] [PATCH 1/3] package/doxygen: disable shared libs for host

[Michael Nosthoff]

doxygen fails to build with BUILD_SHARED_LIBS=ON as it only
for some targets honors this flag and links the rest static.
So enforce BUILD_SHARED_LIBS=OFF for this package.

[Buildroot] [PATCH 3/3] package/pkg-cmake.mk: build host with shared libs

[Michael Nosthoff]

CMake offers the BUILD_SHARED_LIBS flag as a default parameter
and most packages honor them.
Similar to pkg-autotools.mk build host packages always with
BUILD_SHARED_LIBS=ON.
