Make it easy to add custom target executions in the automatic
eclipse configuration generation, for example to call other
standard waf targets from other tools or with specific options.
Add automatic generation of editor language settings for C and C++,
so the automatic code correction uses the correct compiler and
compiler flags, including for example the correct C/C++ standard
so construct from such standards are correctly managed by the IDE.
Correct compiler and flags are automatically generated using the
build environment data gathered during configure phase.
The playground example has been modified to contain some code that
is standard specific to demonstrate the new feature when run under
Eclipse.
When CDT is not included in the project (ie. we just have Python and/or Java) the current implementation would not create automatically a call to waf
for the build stage. This patch adds in such cases an external builder that automates the call to waf without the need to manually configure one.
added support to search and add into source path also generated source
files for both java and python. this is useful when using generated code
(ie. protoc and pyqt5) so browsing in eclipse works correclty adding also
paths where generated code is done.
extended example in playground demostrating generated code
