"""

for some obscure reason, the precompiled header will not be taken if
|
|
all.h is in the same directory as main.cpp
|
|
we recommend to add the header to compile in a separate directory without any sources
|
|
|
|
Note: the #warning will come once when the .h is compiled, it will not come when the .cpp is compiled
|
|
Note: do not forget to set the include paths (include=...)
