What is CMake equivalent of 'configure --prefix=DIR && make all install '?

You can pass in any CMake variable on the command line, or edit cached variables using ccmake/cmake-gui. On the command line,

cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr . && make all install

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.

mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .. && cmake --build . --target install --config Release

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.

The ":PATH" part in the accepted answer can be omitted. This syntax may be more memorable:

cmake -DCMAKE_INSTALL_PREFIX=/usr . && make all install

...as used in the answers here.

Note that in both CMake and Autotools you don't always have to set the installation path at configure time. You can use DESTDIR at install time (see also here) instead as in:

make DESTDIR=<installhere> install

See also this question which explains the subtle difference between DESTDIR and PREFIX.

This is intended for staged installs and to allow for storing programs in a different location from where they are run e.g. /etc/alternatives via symbolic links.

However, if your package is relocatable and doesn't need any hard-coded (prefix) paths set via the configure stage you may be able to skip it. So instead of:

cmake -DCMAKE_INSTALL_PREFIX=/usr . && make all install

you would run:

cmake . && make DESTDIR=/usr all install

Note that, as user7498341 points out, this is not appropriate for cases where you really should be using PREFIX.

The way I build CMake projects cross platform is the following:

/project-root> mkdir build
/project-root> cd build
/project-root/build> cmake -G "<generator>" -DCMAKE_INSTALL_PREFIX=stage ..
/project-root/build> cmake --build . --target=install --config=Release

• The first two lines create the out-of-source build directory
• The third line generates the build system specifying where to put the installation result (which I always place in ./project-root/build/stage - the path is always considered relative to the current directory if it is not absolute)
• The fourth line builds the project configured in . with the buildsystem configured in the line before. It will execute the install target which also builds all necessary dependent targets if they need to be built and then copies the files into the CMAKE_INSTALL_PREFIX (which in this case is ./project-root/build/stage. For multi-configuration builds, like in Visual Studio, you can also specify the configuration with the optional --config <config> flag.
• The good part when using the cmake --build command is that it works for all generators (i.e. makefiles and Visual Studio) without needing different commands.

Afterwards I use the installed files to create packages or include them in other projects...

Starting with CMake 3.15, the correct way of achieving this would be using:

cmake --install <dir> --prefix "/usr"
