This would also be highly inconvenient as one usually expects that the
"install" target depends on the "all" target, so a "make install" will
ensure that the installed package is up-to-date, i.e. completely built.

Drop the ALL clause in the ADD_CUSTOM_TARGET() command, but if I
understand correctly, this contradicts your actual intention since
you would need to trigger the "install_after_all" target explicitly.
Alternatively, you might try to call the "cmake_install.cmake" script
by the custom command instead of triggering the "install" target; it
should be quite the same, but doesn't retrigger the "all" target. On
*nix, I can see the following CMakeLists.txt work and do what you
probably want, in particular without any dependency cycles:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8 FATAL_ERROR)
PROJECT(INSTALL_AFTER_ALL C)
SET(CMAKE_VERBOSE_MAKEFILE ON)
FILE(WRITE ${CMAKE_BINARY_DIR}/main.c "int main(void){return 0;}\n")
ADD_EXECUTABLE(main main.c)
INSTALL(TARGETS main RUNTIME DESTINATION bin)
ADD_CUSTOM_TARGET(install_after_all ALL
COMMAND ${CMAKE_COMMAND} -P ${CMAKE_BINARY_DIR}/cmake_install.cmake)
ADD_DEPENDENCIES(install_after_all main)
However, ATM, I can't check if this works with Visual Studio, too.
