Hello.
I really can't understand what's going on. Trying to compile my project
for android, setting all kinds of things to get it done. I've tried 3.8.0,
3.7.2 and 3.6.2, with the same result. The below extracts are from running
3.6.2
Running with --debug and --trace, I see:
/usr/share/cmake/Modules/FindPkgConfig.cmake(91):
_pkgconfig_set(JSONC_CFLAGS ${_pkgconfig_invoke_result} )
/usr/share/cmake/Modules/FindPkgConfig.cmake(64): set(JSONC_CFLAGS
-I/tmp/arm-23/include/json-c;-I/tmp/arm-23/include CACHE INTERNAL )
I ran strace, and I can see pkg-config returning paths normally, just spaces.
Running make on the generated makefiles:
/tmp/arm-23/bin/arm-linux-androideabi-gcc -g -ggdb -O0 --std=c99
-isystem/home/vps/ws/EF/DMClient/android_src/http-parser
-isystem/usr/include
-isystem/home/vps/ws/EF/DMClient/android_src/wslay/lib/includes
-I/tmp/arm-23/include/json-c;-I/tmp/arm-23/include -isystem
/tmp/arm-23/include -isystem /tmp/arm-23/include/libxml2 -o
CMakeFiles/dmclient.dir/config.c.o -c
/home/vps/ws/EF/DMClient/config.c
The semicolons are in the ./CMakeFiles/node_editor.dir/flags.make
The CMakeLists.txt has this line:
pkg_check_modules(JSONC REQUIRED json-c openssl)
At this point, I'm running CMake without any fancy command, the compiler
location and such are derived from environment variables.
I tried using the NDK flags (with 3.8, and using toolchain), but then
realized this reproduces even without them (and on 3.6)
Any idea what drags in those semicolons?
CMake uses semicolons to separate list elements:
https://cmake.org/cmake/help/latest/manual/cmake-language.7.html#lists
Some CMake commands / variables / properties expect ";"-separated lists
(e.g. target_compile_options(), COMPILE_OPTIONS) and some expect strings
with whitespace separated arguments (e.g. CMAKE_C_FLAGS, COMPILE_FLAGS).
Presumably you are feeding the list to something that expects the latter.
