loosen compiler requirements

v1.3.3

lint

Print when Make+Cmake disabled

v1.3.1

disable test for repeated with make

cleanup examples

• put same name submodule, module into src/same.f90
• removed unneeded compiler options for clarity
• general cleanup of cruft

implicit none, setup.cmake

• use setup.cmake for simpler build and test
• put implicit none everywhere to reflect better how submodules are actually used.

correct CMake build options

the cmake generators didn't work for this type of applications

cmake cleanup, external module name change

• Update CMake to allow non-Make generators to fully build project
• modernize CMake to use target properties rather than throwing everything in CMAKE_BINARY_DIR
• cleanup Meson
• rename external module to constants for better example usage

more stuff cmake can't build that meson can

cmake: disabled examples that it can't build due to bugs in Cmake submodule syntax.
Meson is fine with all examples.

correctness

Thanks to @zbeekman correct module naming to avoid module namespace clashes.

Noted that even CMake 3.16.2 cannot handle module pure function foo() but Meson can.

initial release

cmake/meson add external.f90 for subproject/externalProject demo
