CMake cannot open "ucrtd.lib"

Question

My problem is similar to this one: Problems generating solution for VS 2017 with CMake, but the solution doesn't work for me.

When run cmake in Developer Command Prompt for VS 2017, I got the error (from CMakeError.log):

LINK : fatal error LNK1104: Cannot open file "ucrtd.lib" [E:\Projects\My Project\VS\CMakeFiles\3.14.4\CompilerIdC\CompilerIdC.vcxproj]

But the file ucrtd.lib is located in the Windows Kits folder.

echo %LIB%

D:\Program Files (x86)\Microsoft Visual Studio 2017 Community\VC\Tools\MSVC\14.16.27023\lib\x86;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6.1\lib\um\x86;C:\Program Files (x86)\Windows Kits\10\lib\10.0.17763.0\ucrt\x86;C:\Program Files(x86)\Windows Kits\10\lib\10.0.17763.0\um\x86;

dir "C:\Program Files (x86)\Windows Kits\10\lib\10.0.17763.0\ucrt\x86\" /w /b

libucrt.lib
libucrtd.lib
ucrt.lib
ucrtd.lib

And I also try to manually run the build command listed in the CMakeError.log, it succeeds, no error.

CL.exe /c /nologo /W0 /WX- /diagnostics:classic /Od /Oy- /D _MBCS /Gm- /EHsc /RTC1 /MDd /GS /fp:precise /Zc:wchar_t /Zc:forScope /Zc:inline /Fo"Debug\" /Fd"Debug\vc141.pdb" /Gd /TC /analyze- /FC /errorReport:queue CMakeCCompilerId.c

link.exe /ERRORREPORT:QUEUE /OUT:".\CompilerIdC.exe" /INCREMENTAL:NO /NOLOGO kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib /MANIFEST /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /manifest:embed /PDB:".\CompilerIdC.pdb" /SUBSYSTEM:CONSOLE /TLBID:1 /DYNAMICBASE /NXCOMPAT /IMPLIB:".\CompilerIdC.lib" /MACHINE:X86 /SAFESEH Debug\CMakeCCompilerId.obj

So it seems like cmake didn't recognize the environment variables, or did I miss some important steps?

cmake version is 3.14.4
visual studio version is 15.9.7

Did you try to explicitly tell CMake to target the specific version of Windows you have installed: -DCMAKE_SYSTEM_VERSION=10.0.17763.0 ? See the post here. — squareskittles
Great! Added this as an answer. The aforementioned post shows that CMake checks some registry values for the Windows Kits root folder, and may find the wrong one first if multiple VS versions are installed. — squareskittles

As mentioned in this CMake forum, it may be necessary to explicitly tell CMake which specific Windows version you have installed. Considering you have version 10.0.17763.0 installed, including the following definition will direct CMake to that version:

cmake -DCMAKE_SYSTEM_VERSION=10.0.17763.0

Here are the docs for CMAKE_SYSTEM_VERSION.
