CMAKE_INSTALL_PREFIX has a different semantic meaning than ${prefix}[1]. cmake
treats
CMAKE_INSTALL_PREFIX the same as the DESTDIR environment variable.
CMAKE_INSTALL_PREFIX and DESTDIR are different and used together [1]:
[...] install the concerned software using the installation prefix [...]
prepended with the DESTDIR [...]
Setting
CMAKE_INSTALL_PREFIX to ${prefix} is inappropriate.
Why? It configures the prefix.
${prefix} is set to "/usr" in bitbake.conf. The default
CMAKE_INSTALL_PREFIX is "/usr/local"
This will likely break a lot of cmake recipes that have do_post_install hacks
to get
around this bug.
What hacks do you mean?
