Which files did you update? Adding support for third-party libraries typically involves doing the following:

Add cmake/modules/FindFOO.cmake

Add a configure-time option to CMakeOptions.txt:

option(ENABLE_FOO        "Build with FOO support" ON)

Tell CMakeLists.txt to look for the library:

ws_find_package(FOO ENABLE_FOO HAVE_FOO)

Add a compile-time option to cmakeconfig.h.in:

/* Define to use foo library */
#cmakedefine HAVE_FOO 1

Update the various OS setup scripts (tools/*setup*).

Adding the library to win-setup.ps1 requires action by the operations team, as does installing it on the build 
machines. It's a bit more convenient (but not necessary) if the library is supported by vcpkg on Windows.
