I agree that this change is a weird one to propose "upstream" (i.e. here), and almost excluded it.
Yes, it's a standard approach for MacPorts to use a patch file to insert a placeholder into files, that is replaced with the actual prefix path later on. It's my version of that approach to use a placeholder that evaluates to the default prefix path under standard path normalisation rules.

Looking at the issue again, I realise that another approach is possible too here: using a variable that is already available to cmake.

This is the cmake invocation is it current is generated through my Portfile; ${CMAKE_INSTALL_PREFIX} would be the obvious choice (i.e. //opt//local//include/openjpeg-1.5 would become something like ${CMAKE_INSTALL_PREFIX}/include/openjpeg-1.5?) :

`cmake -DCMAKE_INSTALL_PREFIX=${prefix} -DCMAKE_VERBOSE_MAKEFILE=ON -DCMAKE_COLOR_MAKEFILE=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DCMAKE_INSTALL_RPATH=${prefix}/lib -DCMAKE_INSTALL_NAME_DIR=${prefix}/lib -DCMAKE_SYSTEM_PREFIX_PATH="${prefix};/usr" -DCMAKE_FIND_FRAMEWORK=LAST -Wno-dev -DCMAKE_MODULE_PATH="${prefix}/share/cmake/Modules;${prefix}/share/cmake/Modules" -DBUILD_SHARED_LIBS=ON -DBUNDLE_INSTALL_DIR=/Applications/MacPorts/KDE4 -DKDE_DISTRIBUTION_TEXT="MacPorts/Mac OS X" -DQT_QT_INCLUDE_DIR=${prefix}/include/qt4  -DQT_QMAKESPEC=macx-g++  -DQT_ZLIB_LIBRARY=${prefix}/lib/libz.dylib  -DQT_PNG_LIBRARY=${prefix}/lib/libpng.dylib -DDOCBOOKXSL_DIR=${prefix}/share/xsl/docbook-xsl -DGETTEXT_INCLUDE_DIR=${prefix}/include -DGETTEXT_LIBRARY=${prefix}/lib/libgettextlib.dylib -DGIF_INCLUDE_DIR=${prefix}/include -DGIF_LIBRARY=${prefix}/lib/libgif.dylib -DJASPER_INCLUDE_DIR=${prefix}/include -DJASPER_LIBRARY=${prefix}/lib/libjasper.dylib -DJPEG_INCLUDE_DIR=${prefix}/include -DJPEG_LIBRARY=${prefix}/lib/libjpeg.dylib -DLBER_LIBRARIES=${prefix}/lib/liblber.dylib -DLDAP_INCLUDE_DIR=${prefix}/include -DLDAP_LIBRARIES=${prefix}/lib/libldap.dylib -DLIBEXSLT_INCLUDE_DIR=${prefix}/include -DLIBEXSLT_LIBRARIES=${prefix}/lib/libexslt.dylib -DLIBICALSS_LIBRARY=${prefix}/lib/libicalss.dylib -DLIBICAL_INCLUDE_DIRS=${prefix}/include -DLIBICAL_LIBRARY=${prefix}/lib/libical.dylib -DLIBINTL_INCLUDE_DIR=${prefix}/include -DLIBINTL_LIBRARY=${prefix}/lib/libintl.dylib -DLIBXML2_INCLUDE_DIR=${prefix}/include/libxml2 -DLIBXML2_LIBRARIES=${prefix}/lib/libxml2.dylib -DLIBXML2_XMLLINT_EXECUTABLE=${prefix}/bin/xmllint -DLIBXSLT_INCLUDE_DIR=${prefix}/include -DLIBXSLT_LIBRARIES=${prefix}/lib/libxslt.dylib -DMYSQLD_EXECUTABLE=${prefix}/libexec/mysqld -DMYSQL_INCLUDE_DIR=${prefix}/include/mysql5/mysql -DMYSQL_LIB_DIR=${prefix}/lib/mysql5/mysql -DMYSQLCONFIG_EXECUTABLE=${prefix}/bin/mysql_config5 -DOPENAL_INCLUDE_DIR=/System/Library/Frameworks/OpenAL.framework/Headers -DOPENAL_LIBRARY=/System/Library/Frameworks/OpenAL.framework -DPNG_INCLUDE_DIR=${prefix}/include -DPNG_PNG_INCLUDE_DIR=${prefix}/include -DPNG_LIBRARY=${prefix}/lib/libpng.dylib -DTIFF_INCLUDE_DIR=${prefix}/include -DTIFF_LIBRARY=${prefix}/lib/libtiff.dylib -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo -DCMAKE_STRIP:FILEPATH=/bin/echo -DPhonon_DIR=${prefix}/share/cmake/modules/phonon -DICONV_INCLUDE_DIR=${prefix}/include -DICONV_LIBRARIES=${prefix}/lib/libiconv.dylib -DFreeTDS_INCLUDE_DIR=${prefix}/include/freetds -DFreeTDS_LIBRARIES=${prefix}/lib/libsybdb.dylib -DCMAKE_C_FLAGS_RELEASE="-DNDEBUG" -DCMAKE_CXX_FLAGS_RELEASE="-DNDEBUG" -DCMAKE_OSX_ARCHITECTURES="x86_64" -DCMAKE_OSX_DEPLOYMENT_TARGET="10.9" -DCMAKE_OSX_SYSROOT="/" ../${worksrcpath}`

The header and library search paths required for OpenJPEG, libpqxx and OpenVC are added using `//opt//local//` which is of course equivalent to `/opt/local` but easier to search-and-replace with the true install location in MacPorts' post-patch stage.
