[muparser] Linkage not hardcoded/ wide character set not hardcoded

[Neumann-A]

Port needs:

if(VCPKG_LIBRARY_LINKAGE STREQUAL "static")
    vcpkg_replace_string("${CURRENT_PACKAGES_DIR}/include/muParserFixes.h" "#ifndef MUPARSER_STATIC" "#if 0")
else()
    vcpkg_replace_string("${CURRENT_PACKAGES_DIR}/include/muParserFixes.h" "#ifndef MUPARSER_STATIC" "#if 1")
endif()

and

vcpkg_replace_string("${CURRENT_PACKAGES_DIR}/include/muParserDef.h" "#if defined(_UNICODE)" "#if 0")
vcpkg_replace_string("${CURRENT_PACKAGES_DIR}/include/muParserDLL.h" "#ifndef _UNICODE" "#if 1")

or make it depend the later two on ENABLE_WIDE_CHAR
