We support multiple commands per external project step by using
the COMMAND keyword. Document this behavior and show an example.
While at it, document that shell operators and current working
directory behavior is not defined.
CMake requires the top-level CMakeLists.txt to contain a direct call to
the project() command and will insert one if there is not. Document
this requirement since some authors have tried to use include() to load
a file calling the project command.
If a non-IMPORTED library is added to the INTERFACE_LINK_LIBRARIES
of a IMPORTED target, the non-IMPORTED target needs to become a
target dependency and link dependency of the consuming target.
This is already the case since commit 30962029 (Make targets depend
on the link interface of their dependees, 2012-12-26), and fixed in
the parent commit, so test that it works.
This was missing from commit 30962029 (Make targets depend on the
link interface of their dependees., 2012-12-26), which caused
only immeditate entries of the link interface to become target
depends.
Add to the brief documentation of the Visual Studio 10, 11, and 12
generators the corresponding VS product year. Clarify that VS11 is for
Visual Studio 2012, and VS12 is for Visual Studio 2013.
The line
set( ${basename}_LIBRARY )
removes the normal variable, but if the corresponding cached variable is
present then line
list( APPEND ${basename}_LIBRARY optimized "${_libname}" )
uses that and fails. Replace the original line with
set( ${basename}_LIBRARY "" )
to set the normal variable to empty instead of unsetting it.
In CMakeTestFortranCompiler we build a test program using a Fortran 90
construct to check whether the compiler supports the language. Some
compilers have options to require explicit variable types. Fix the test
program to use an explicit variable type so it passes under such a
configuration.
