pkg-cmake.mk: refactor the toolchainfile.cmake generation This patch introduces a toolchainfile.cmake.in template which is filled by Buildroot. Using a toolchainfile.cmake.in template file allows to avoid overloading quoting and/or escaping and it becomes much more similar to the resulting file. This patch also cleans up the quoting style.

toolchainfile.cmake.in: do not force the CMAKE_{C, CXX}_FLAGS to the cache Fix #7280 [1] When the FORCE option is passed to the set command, the variable is added/updated in the CMake cache every single time CMake processes this command. Because the toolchainfile.cmake prepends architecture/toolchain flags to the CMAKE_{C,CXX}_FLAGS, this makes the CFLAGS being updated in the generated Makefiles each time one reconfigures its project. So it forces the compilation of everything, even when nothing has changed.

pkg-cmake.mk: enable ccache for cmake packages This patch updates the generated toolchainfile.cmake to use ccache. When toolchainfile.cmake is used inside Buildroot, using ccache during the build is driven by a CMake knob: USE_CCACHE, automatically set by the cmake-package infrastructure and reflecting the BR2_CCACHE value. Since this toolchainefile.cmake file can be used outside Buildroot, and this file also set a couple of things (among these: the sysroot cflag, some pkg-config environment variables), it is important to set the compiler variables as well to keep the consistency of the cross-compilation configuration. So, when it is used outside Buildroot, using ccache for the build is driven by the ccache program availability. Note that using ccache for the build is achieved by setting the *_ARG1 CMake variables to let CMake use ccache without failing in detecting the compiler.
