I am attempting to create a new port for VCPKG, for the Arabica project. The vcpkg install command is failing. The first error is as follows.
...\include\XPath/impl/xpath_namespace_context.hpp(7,10):
fatal error C1083: Cannot open include file: 'boost/shared_ptr.hpp':
No such file or directory [D:\vcpkg\buildtrees\arabica\x64-windows-dbg\mangle.vcxproj]
The thing is that this file is installed in the VCPKG include directory. To be precise it is installed at D:\vcpkg\installed\x64-windows\include\boost\shared_ptr.hpp.
The command used to compile the file is as follows.
...\CL.exe /c /I"D:\vcpkg\buildtrees\arabica\x64-windows-dbg\include" /I"D:\vcpkg\buildtrees\arabica\src\0-February-67b234ed05\include" /Z7 /W3 /WX- /diagnostics:column /MP /Od /Ob0 /D WIN32 /D _WINDOWS /D _DEBUG /D ARABICA_DEBUG /D ARABICA_NOT_USE_PRAGMA_LINKER_OPTIONS /D "CMAKE_INTDIR=\"Debug\"" /D _MBCS /Gm- /EHsc /RTC1 /MDd /GS /fp:precise /Zc:wchar_t /Zc:forScope /Zc:inline /GR /Fo"xgrep.dir\Debug\\" /Fd"xgrep.dir\Debug\vc142.pdb" /Gd /TP /errorReport:queue /utf-8 "D:\vcpkg\buildtrees\arabica\src\0-February-67b234ed05\examples\XPath\xgrep.cpp"
If I could just get VCPKG to add the /I"D:\vcpkg\installed\x64-windows\include" command line argument it would work.
The contents of my CONTROL file is as follows.

This is failing with the compiler error I mentioned above and several other due to missing Boost header files. None of these compiler errors would occur if it would just include the VCPKG include directory in the list of include directories since Boost is already installed and the CONTROL file states that this library depends on Boost.
Is there a magical incantation I need to pass to either vcpkg_configure_cmake or vcpkg_install_cmake that says "include the VCPKG include directory in the include path?"
If I could just get VCPKG to add the /I"D:\vcpkg\installed\x64-windows\include" command line argument it would work.
You don't need to convince vcpkg to do that but cmake. So just replace your vcpkg_configure_cmake call with:
vcpkg_configure_cmake(
SOURCE_PATH ${SOURCE_PATH}
PREFER_NINJA
OPTIONS -DBUILD_WITH_BOOST=ON
)
to actually do the find_package call for boost in your CMakeLists.txt. (Actually BUILD_WITH_BOOST seems like a non option since it is build requirement?!?!). It is also better to link against the Boost::headers target since this would have thrown a CMake error if the target is unavailable.
It will then build but fail to link with the following errors (triplet x64-windows):
taggle.cpp.obj : error LNK2001: unresolved external symbol "public: static int const Arabica::SAX::Schema::M_ANY" (?M_ANY@Schema@SAX@Arabica@@2HB)
taggle.cpp.obj : error LNK2001: unresolved external symbol "public: static int const Arabica::SAX::Schema::M_EMPTY" (?M_EMPTY@Schema@SAX@Arabica@@2HB)

taggle.exe : fatal error LNK1120: 7 unresolved externals
So I assume your CMakeLists.txt has logical errors if internal symbols cannot be found. (Building x64-windows-static is successful so it is a symbol visibility problem)
you also need to add
file(REMOVE_RECURSE "${CURRENT_PACKAGES_DIR}/debug/include")
to your portfile.cmake
