"Generator expressions are evaluted during build system generation " \
"to produce information specific to each build configuration. " \
"Valid expressions are:\n" \
" $<0:...> = empty string (ignores \"...\")\n" \
" $<1:...> = content of \"...\"\n" \
" $<CONFIG:cfg> = '1' if config is \"cfg\", else '0'\n" \
" $<CONFIGURATION> = configuration name\n" \
" $<BOOL:...> = '1' if the '...' is true, else '0'\n" \
" $<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'\n" \
" $<ANGLE-R> = A literal '>'. Used to compare " \
"strings which contain a '>' for example.\n" \
" $<COMMA> = A literal ','. Used to compare " \
"strings which contain a ',' for example.\n" \
" $<TARGET_NAME:...> = Marks ... as being the name of a " \
"target. This is required if exporting targets to multiple " \
"dependent export sets. The '...' must be a literal name of a " \
"target- it may not contain generator expressions.\n" \
" $<INSTALL_INTERFACE:...> = content of \"...\" when the property " \
"is exported using install(EXPORT), and empty otherwise.\n" \
" $<BUILD_INTERFACE:...> = content of \"...\" when the property " \
"is exported using export(), or when the target is used by another " \
"target in the same buildsystem. Expands to the empty string " \
"otherwise.\n" \
" $<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)\n" \
" $<TARGET_DEFINED:tgt> = '1' if tgt is a target, else '0'\n" \
" $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)\n" \
" $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)\n" \
"where \"tgt\" is the name of a target. " \
"Target file expressions produce a full path, but _DIR and _NAME " \
"versions can produce the directory and file name components:\n" \
" $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>\n" \
" $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>\n" \
" $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>\n" \
"\n" \
" $<TARGET_PROPERTY:tgt,prop> = The value of the property prop " \
"on the target tgt.\n" \
"Note that tgt is not added as a dependency of the target this " \
"expression is evaluated on.\n" \
" $<LINKED:item> = An empty string if item is not a " \
"target. If item is a target then the " \
"INTERFACE_INCLUDE_DIRECTORIES or INTERFACE_COMPILE_DEFINITIONS " \
"content is read from the target. " \
"This generator expression can only be used in evaluation of the " \
"INCLUDE_DIRECTORIES or COMPILE_DEFINITIONS property. Note that " \
"this expression is for internal use and may be changed or removed " \
"in the future.\n" \
" $<TARGET_POLICY:pol> = '1' if the policy was NEW when " \
"the 'head' target was created, else '0'. If the policy was not " \
"set, the warning message for the policy will be emitted. This " \
"generator expression only works for a subset of policies.\n" \
" $<INSTALL_PREFIX> = Content of the install prefix when " \
"the target is exported via INSTALL(EXPORT) and empty otherwise.\n" \
"Boolean expressions:\n" \
" $<AND:?[,?]...> = '1' if all '?' are '1', else '0'\n" \
" $<OR:?[,?]...> = '0' if all '?' are '0', else '1'\n" \
" $<NOT:?> = '0' if '?' is '1', else '1'\n" \
"where '?' is always either '0' or '1'.\n" \
