Is there a CMake '--install' switch?
CmakeCmake Problem Overview
With reference to this question there is a so-called 'install' phase in CMake. I'm used to run CMake in a sequence that looks like this:
cmake ..
cmake --build . --config Debug
cmake --build . --config Release
Is there a cmake --install command line switch meant to be invoked after this?
Although I figure it is somehow related, I'm not looking for the so called install command here (I perceive this to be a function rather than a command, but this is likely a terminology issue).
Cmake Solutions
Solution 1 - Cmake
No, this switch does not exist (until CMake 3.15, see my other answer).
If a project uses the install command, it generates the target install. You can call it with
cmake --build . --target install
This uses CMake's Build Tool Mode, which is an abstract interface for a couple of commands to the native build tool (e.g. make or Ninja) and can also be used to pass arbitrary arguments to the native build tool.
Solution 2 - Cmake
Beginning with version 3.15, CMake offers an install switch. From the release notes:
> The "cmake(1)" command gained a new "--install" option. This may > be used after building a project to run installation without using > the generated build system or the native build tool.

So you can use
cmake --install <dir> [--prefix <install-dir>]
The optional --prefix flag lets you override the CMAKE_INSTALL_PREFIX.
