Hi,
snapcraft can not build flatbuffers, because /root/parts//install/usr/include is not include as isystem

snapcraft also cannot build this simple test.cpp.
#include <limits.h>
#include <stdio.h>
int main(){ printf("hello"); return 0;}
/usr/bin/c++ -I/root/parts/yabasanshiro/install/usr/include -Wall -pedantic -Werror test.cpp
In file included from test.cpp:1:0:
/root/parts/yabasanshiro/install/usr/include/limits.h:124:3: error: #include_next is a GCC extension [-Werror]
# include_next <limits.h>
when compile param changed from -i to -isystem, it can be build.
/usr/bin/c++ -isystem /root/parts/yabasanshiro/install/usr/include -Wall -pedantic -Werror test.cpp
But in flatbuffers include param is generated by cmake I can not change by hand.
Any help??
