CVPACK Fatal Error CK1028

file compiled /Yc /Yu /Z7; cannot create debug info, recompile all with /Zi

You created two PCH files, one based on the other using the /Z7 compiler option. Only one precompiled type object can be referenced. The only way to use PCH files based on other PCH files is to use the /Zi compiler option to put all types in the .PDB file.
