  • Add fcm in LMDZ5/tools directory

It is no longer needed to have fcm in your environement PATH variable.
Now makelmdz_fcm takes by default this fcm. It is still possible to use
another fcm, using -fcm_path argument in makelmdz_fcm.

21  Declarations in FCM build configuration file</h1>
22
23  <p>The following is a list of supported declarations for the configuration
24  file used by the FCM build system. Unless otherwise stated, the fields in
25  all declaration labels are not case sensitive. Build declarations can be
26  made either in a build configuration file or in an extract configuration
27  file. In the latter case, the prefix "BLD::" must be added at the beginning
28  of each label to inform the extract system that the declaration is a build
29  system declaration. (In a build configuration file, the prefix "BLD::" is
30  optional.)</p>

360        directories under the sub-package. Otherwise, the declaration applies
361        globally. It is worth noting that the build system is not yet clever
362        enough to recognise changes in this declaration in incremental builds.
363        Therefore, users should manually trigger a full build if these
364        statements are modified. The value of this declaration must contain one
365        or two fields (separated by the double colon "::"). The first field
366        denotes the dependency type, and the second field is the dependency
367        target. If the second field is specified, it will only exclude the
368        dependency to the specified target. Otherwise, it will exclude all
