CMake Error at scripts/cmake/vcpkg_replace_string.cmake:12

I tried to build a static x86 build of zlib and the build succeeded, but the library still has dynamic CRT dependencies for some reason?

So, I found zlib-ng and thought I would try to build it as static. The build worked, but the APIs are different and then I noticed a ZLIB_COMPAT CMAKE flag you can set for the build. So, I am trying to do that. I have a custom triplet named x86-windows-static-release-v143.cmake with the following contents:

if(PORT MATCHES "zlib-ng")
    set(VCPKG_CMAKE_CONFIGURE_OPTIONS -DZLIB_COMPAT:BOOL=ON)
endif()
set(VCPKG_TARGET_ARCHITECTURE x86)
set(VCPKG_CRT_LINKAGE static)
set(VCPKG_LIBRARY_LINKAGE static)
set(VCPKG_BUILD_TYPE release)
set(VCPKG_PLATFORM_TOOLSET v143)
set(X_VCPKG_APPLOCAL_DEPS_INSTALL ON)

Running this command-line: vcpkg install zlib-ng:x86-windows-static-release-v143 fails with the following output:

If I take out the port specific 'if' block in the triplet, everything works. Am I doing this wrong?
