source:
`storage/connect/CMakeLists.txt:320-323`:
SET_SOURCE_FILES_PROPERTIES(${MINIZIP_SOURCES} PROPERTIES COMPILE_FLAGS "\
|
$<${have_C__Wmissing_declarations}:-Wno-missing-declarations> \
|
$<${have_C__Wdeclaration_after_statement}:-Wno-declaration-after-statement> \
|
")
|
iiuc,
`have_C__Wdeclaration_after_statement` is set by `MY_CHECK_C_COMPILER_FLAG()` in `cmake/maintainer.cmake`. Unset when `MYSQL_MAINTAINER_MODE=NO`.
and,
`$<${var}:flag>` with empty `var` produces `$<:flag>` – not a known generator expression; CMake aborts generate with a fatal error.
given,
`$<BOOL:x>` evaluates empty to `0`, producing `$<0:flag>` (valid) instead of `$<:flag>` (invalid).
this
SET_SOURCE_FILES_PROPERTIES(${MINIZIP_SOURCES} PROPERTIES COMPILE_FLAGS "\
|
- $<${have_C__Wmissing_declarations}:-Wno-missing-declarations> \
|
- $<${have_C__Wdeclaration_after_statement}:-Wno-declaration-after-statement> \
|
+ $<$<BOOL:${have_C__Wmissing_declarations}>:-Wno-missing-declarations> \
|
+ $<$<BOOL:${have_C__Wdeclaration_after_statement}>:-Wno-declaration-after-statement> \
|
") |
seems to do the trick; build's ok
