I do cmake . && make all install. This works, but installs to /usr/local.
I need to install to a different prefix (for example, to /usr).
What is the cmake and make command line to install to /usr instead of /usr/local?
You can pass in any CMake variable on the command line, or edit cached variables using ccmake/cmake-gui. On the command line,
Would configure the project, build all targets and install to the /usr prefix. The type (PATH) is not strictly necessary, but would cause the Qt based cmake-gui to present the directory chooser dialog.
Some minor additions as comments make it clear that providing a simple equivalence is not enough for some. Best practice would be to use an external build directory, i.e. not the source directly. Also to use more generic CMake syntax abstracting the generator.
You can see it gets quite a bit longer, and isn’t directly equivalent anymore, but is closer to best practices in a fairly concise form… The –config is only used by multi-configuration generators (i.e. MSVC), ignored by others.
