Apparently /DEBUG implicitly disables linker optimizations. This
explicitly re-enables them, giving a 40% reduction in binary sizes and
a very slight runtime speed improvement.
Debug was missing compiler flags, causing MSVC to default it to building
with optimizations enabled (making for a not very useful binary for
actual debugging...). Additionally, the variables were re-organized to
remove some redundancy, the old Release build type was removed, and
RelWithDebInfo was renamed to take its place instead.
Remove unneeded stuff from pre-commit script
The check against an empty commit was not needed (it is only a security for the 1st commit after git init).
It could also possibly pose problems because of the redirection to /dev/null on some windows systems.

Passing -pthread to GCC as a flag makes it both link to libpthread, and make C standard library routines reentrant. This makes the additional explicit links unnecessary.
Additionally, on OSX, this is the default behavior, and clang will print a message about it being unused if it's present there.
These are implicitly linked by Xcode, but with this, you can also build it with any other generator, which does not have this behavior.
CoreFoundation is included as a part of Cocoa (which is an umbrella framework), and Cocoa is generally recommended to link against, rather than its individual components (CoreFoundation, Foundation, libobjc, ...).
This both reduces redundancy in add_executable definitions, and makes it easier to link additional libraries. In particular, extra libraries are needed on OSX - see next commit.
This enables the /MP compiler flag, which parallelizes builds of by
distributing compilation of individual object files across workes
processes, instead of being limited to per-project parallelism.
Reduces the time for a full compile from 72 s to 45 s on my machine.
Several cleanups to the buildsystem:
- Do better factoring of common libs between platforms.
- Add support to building on Windows.
- Remove Qt4 support.
- Re-sort file lists and add missing headers.
This should fix the GL loading errors that occur in some drivers due to
the use of deprecated functions by GLEW. Side benefits are more accurate
auto-completion (deprecated function and symbols don't exist) and faster
pointer loading (less entrypoints to load). In addition it removes an
external library depency, simplifying the build system a bit and
eliminating one set of binary libraries for Windows.
After adding FindGLEW.cmake to externals, the variable call for the GLEW include path needed to be revised.
Append flags on OSX, rather than overwrite them.
I realized that GCC_COMPILE_FLAGS was changed to CMAKE_CXX_FLAGS mistakenly, so both were changed to a more platform-independent name.
