On what platform did you build?  That source file is used only on
Windows platforms.  It won't compile at all on Linux or OS X hosts
so it is not expected to re-compile after modification on those
platforms.

After compiling, run

 bin/ctest

to run the tests.  If you used a VS (or Xcode) generator then run

 bin/Debug/ctest -C Debug

where "Debug" is whatever configuration you built after generating.

You don't actually have to use the bootstrap script to build for
development.  You can configure/build CMake with an already-installed
CMake.  This is required on Windows to build with VS.  With this
approach you should run the tests using the ctest that comes next to
the already-installed cmake you ran to configure the build tree.
