+Subject: [PATCH] fix: Allow for ninja and collier to be shared libraries
+
+* It is valid for external instances of ninja and collier to be shared libraries,
+  and so accept them if they are found when a static libray version is not.

+  summary: 'MadGraph5_aMC@NLO'
+  description: |
+    MadGraph5_aMC@NLO is a framework that aims at providing all the elements
+    necessary for SM and BSM phenomenology, such as the computations of cross
+    sections, the generation of hard events and their matching with event
+    generators, and the use of a variety of tools relevant to event manipulation
+    and analysis.
+    Processes can be simulated to LO accuracy for any user-defined Lagrangian,
+    and the NLO accuracy in the case of models that support this kind of calculations
+    &mdash; prominent among these are QCD and EW corrections to SM processes.
+    Matrix elements at the tree- and one-loop-level can also be obtained.
+
+    MadGraph5_aMC@NLO is the new version of both MadGraph5 and aMC@NLO that unifies
+    the LO and NLO lines of development of automated tools within the MadGraph family.
+    As such, the code allows one to simulate processes in virtually all configurations
+    of interest, in particular for hadronic and e+e- colliders; starting from version
+    3.2.0, the latter include Initial State Radiation and beamstrahlung effects.
