103dnl ROOTAUXLIBS Auxilary libraries and linker flags for ROOT
104dnl ROOTAUXCFLAGS Auxilary compiler flags

106dnl
107dnl The macro will fail if root-config and rootcint isn't found.

175dnl Autoconf macro to check conditions for an HLT module
176dnl - header dependencies
177dnl - library dependencies
178dnl - AliRoot availability
179dnl The macro also exports the --enable/--disable option for the
180dnl module.
181dnl
182dnl Synopsis:
183dnl
184dnl ROOT_PATH([module],
185dnl [headers], [additional CPPFLAGS],
186dnl [libraries], [LD flags], [LIBS],
187dnl [circ libraries], [LD flags], [LIBS])
188dnl
189dnl First argument is the module name.
190dnl
191dnl Arg 2 and 3 allow to check a list of header files and to specify
192dnl additional CPPFLAGS which might be necessary to perform the checks.
193dnl
194dnl Arg 4 to 6 allow to check a list of libraries, with additional
195dnl LDFLAGS and LIBS to be specified.
196dnl
197dnl Arg 7 to 9 is the same for libraries with circular dependencies
198dnl among each other.
199dnl
200dnl Return:
201dnl enable_module=yes
202dnl - AliRoot was found &&
203dnl - header files found &&
204dnl - module not disabled
205dnl
206dnl enable_module=no...requires.AliRoot
207dnl - AliRoot not found
208dnl
209dnl enable_module=missheader
210dnl - one of the specified header files is missing
211dnl
212dnl Libraries are probed and the variable ALIHLTMODULE_LIBS is set to
213dnl all libraries which could be found.
