IMO you ask for trouble when you manually inject -DFRMT_mrsid=ON into
CFLAGS and CXXFLAGS. This is CMake input ("ON"!). Let the configuration
do that for you. Did configuration successfully detect the dependency?
Check the config logs.

I am getting the following link errors when building my application in

I am linking statically to GDAL built as a static library with vcpkg
(which builds without error). I am using a custom x86-windows.cmake
file with vcpkg, customized mainly to include MrSID and ECW
functionality in GDAL. I have pasted the cmake text at the bottom of
this email.
From what I can see in the GDAL code, it's behaving as if
gdal/frmts/mrsid/mrsiddataset.cpp (which contains the function
GDALRegister_MrSID) wasn't compiled into the library, yet the
following code in frmts/gdalallregister.cpp was compiled.
#ifdef FRMT_mrsid
GDALRegister_MrSID();
#endif
Can you help me understand how this could happen? What actually
controls whether gdal/frmts/mrsid/mrsiddataset.cpp gets compiled into
the library?
